Werner Lemberg 40911094 2000-11-03T07:57:51 Don't access freed variables...
Werner Lemberg e4b32a5d 2000-10-31T20:42:18 Removing trailing whitespace.
David Turner 47c14b9d 2000-10-27T00:53:16 fixing a small bug in FT_Glyph_To_Bitmap: the glyph advance wasn't copied to the bitmap !!
Werner Lemberg 5a96b07c 2000-10-17T14:29:48 Fixed two typos spotted by Ryan Martindale <ryan@qsicorp.com>.
Werner Lemberg a7096374 2000-10-11T23:31:12 Added new `ft_glyph_bbox_unscaled' enum; fixing documentation of FT_Glyph_Get_CBox(). ftnames.c has been omitted from the Makefile.
Werner Lemberg 8728f294 2000-08-23T17:32:42 Formatting, small fixes. Adding copyright notices etc.
David Turner 97488074 2000-08-22T22:36:33 the psaux module is now nearly completed the "type1z" driver uses it to parse Type 1 charstrings (not to parse the Type 1 token stream yet though)..
David Turner c38ddff8 2000-08-21T04:43:01 fixed a _serious_ bug in FT_Glyph_Get_CBox
Werner Lemberg 97b2de58 2000-07-10T00:06:22 More formatting. Synchronizing docu in include/freetype with src/base.
David Turner c6a92202 2000-07-04T18:12:13 various clean-ups: - using FT_UNUSED instead of UNUSED - using FT_LONG64 and FT_INT64 instead of LONG64 & INT64 - using FT_SIZEOF_INT & FT_SIZEOF_LONG instead of... - removed the #ifdefs that used SIZEOF_INT, instead we now use FT_Int32 and FT_UInt32 when needed to support 32-bits quantity correctly on 64-bits systems..
Werner Lemberg aa8c7da0 2000-07-04T03:37:18 Don't use -lefence in the demo Makefile. Added C++ guards in ftmodule.h Fix error check in ftglyph.c Formatting; adding copyrights; fixing documentation
David Turner d18388e4 2000-07-03T15:00:49 fixed a few 64-bit related bugs in "sfnt/ttload.c" and "base/ftstream.c" Note that "TT_PCLT" was incorrectly defined in <freetype/tttables.h>
Werner Lemberg 5811c7c3 2000-07-02T13:53:16 Formatting. Fixed some errors which prevented compiling.
Werner Lemberg a8bbc267 2000-07-01T14:06:46 Formatting as usual... Adding trivial argument checking to some functions. Added dynamic driver interface to cidriver. Minor `version' fixes for macfont and psnames modules. Removed unnecessary files
David Turner f9ca2bb5 2000-06-30T23:12:55 managed to re-design entirely the API in <freetype/ftglyph.h> It is now really the "glyph factory" that Stefan was probably dreaming about.. fixed some recent formatting errors from Werner ;-) cleaned up the demonstration programs from most of the rust that they had, though I'm sure someone is going to re-format them really soon !! "ftstring" now uses the new ftglyph.h API, and is now faster and smaller.. yep..
Werner Lemberg deb4e983 2000-06-29T03:14:25 Formatting... Preprocessor lines now always start the line. Improved error handling in `base' module. Fixed a out-of-bounds error in ttgload.
Werner Lemberg a929ba9b 2000-06-25T06:47:11 applying formatting again
David Turner f0df85ba 2000-06-22T00:17:42 - MAJOR INTERNAL REDESIGN: A lot of internal modifications have been performed lately on the source in order to provide the following enhancements: - more generic module support: The FT_Module type is now defined to represent a handle to a given module. The file <freetype/ftmodule.h> contains the FT_Module_Class definition, as well as the module-loading public API The FT_Driver type is still defined, and still represents a pointer to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module, FT_Get_Driver by FT_Get_Module, etc.. - support for generic glyph image types: The FT_Renderer type is a pointer to a module used to perform various operations on glyph image. Each renderer is capable of handling images in a single format (e.g. ft_glyph_format_outline). Its functions are used to: - transform an glyph image - render a glyph image into a bitmap - return the control box (dimensions) of a given glyph image The scan converters "ftraster.c" and "ftgrays.c" have been moved to the new directory "src/renderer", and are used to provide two default renderer modules. One corresponds to the "standard" scan-converter, the other to the "smooth" one. The current renderer can be set through the new function FT_Set_Renderer. The old raster-related function FT_Set_Raster, FT_Get_Raster and FT_Set_Raster_Mode have now disappeared, in favor of the new: FT_Get_Renderer FT_Set_Renderer see the file <freetype/ftrender.h> for more details.. These changes were necessary to properly support different scalable formats in the future, like bi-color glyphs, etc.. - glyph loader object: A new internal object, called a 'glyph loader' has been introduced in the base layer. It is used by all scalable format font drivers to load glyphs and composites. This object has been created to reduce the code size of each driver, as each one of them basically re-implemented its functionality. See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for more information.. - FT_GlyphSlot had new fields: In order to support extended features (see below), the FT_GlyphSlot structure has a few new fields: linearHoriAdvance: this field gives the linearly scaled (i.e. scaled but unhinted) advance width for the glyph, expressed as a 16.16 fixed pixel value. This is useful to perform WYSIWYG text. linearVertAdvance: this field gives the linearly scaled advance height for the glyph (relevant in vertical glyph layouts only). This is useful to perform WYSIWYG text. Note that the two above field replace the removed "metrics2" field in the glyph slot. advance: this field is a vector that gives the transformed advance for the glyph. By default, it corresponds to the advance width, unless FT_LOAD_VERTICAL_LAYOUT was specified when calling FT_Load_Glyph or FT_Load_Char bitmap_left: this field gives the distance in integer pixels from the current pen position to the left-most pixel of a glyph image WHEN IT IS A BITMAP. It is only valid when the "format" field is set to "ft_glyph_format_bitmap", for example, after calling the new function FT_Render_Glyph. bitmap_top: this field gives the distance in integer pixels from the current pen position (located on the baseline) to the top-most pixel of the glyph image WHEN IT IS A BITMAP. Positive values correspond to upwards Y. loader: this is a new private field for the glyph slot. Client applications should not touch it.. - support for transforms and direct rendering in FT_Load_Glyph: Most of the functionality found in <freetype/ftglyph.h> has been moved to the core library. Hence, the following: - a transform can be specified for a face through FT_Set_Transform. this transform is applied by FT_Load_Glyph to scalable glyph images (i.e. NOT TO BITMAPS) before the function returns, unless the bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags.. - once a glyph image has been loaded, it can be directly converted to a bitmap by using the new FT_Render_Glyph function. Note that this function takes the glyph image from the glyph slot, and converts it to a bitmap whose properties are returned in "face.glyph.bitmap", "face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original native image might be lost after the conversion. - when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph and FT_Load_Char functions will call FT_Render_Glyph automatically when needed.
Werner Lemberg 4e6dd858 2000-06-05T05:26:15 freetype.h: Adding ft_encoding_xxx values for some CJK encodings. Fixing copyright notice on many files. Changed some tracing levels. A lot of formatting, fixing documentation etc. as usual.
Werner Lemberg eb81e378 2000-06-03T06:03:11 More preparation for tracing. Formatting.
Werner Lemberg 2fbf7e43 2000-06-02T00:01:14 Added a lot of error checking code to the exported functions in the `base' subdir (not complete yet).
Werner Lemberg f13e6333 2000-05-30T16:49:14 Formatting; minor improvements.
David Turner 1fb6eea7 2000-05-24T00:31:14 EXPORT_DEF renamed to FT_EXPORT_DEF + reformating/spacing
David Turner e49ab25c 2000-05-16T23:44:38 formatting - removed trailing spaces
David Turner bfe2f98f 2000-05-12T12:17:15 a new massive grunt work. Redefined the EXPORT_DEF, EXPORT_FUNC, BASE_DEF and BASE_FUNC macros to let them take an argument.. This is needed to compile the library as a DLL on some platforms that have different compiler conventions..
David Turner efce08d6 2000-05-11T18:23:52 major re-organisation of the FreeType 2 directory hierarchy
David Turner f3823281 2000-05-05T13:11:36 added experimental emboldening/outlining code. This is incomplete and will not compile so turned off
David Turner 37379e21 2000-03-28T11:22:31 major changes to the library: - there is now a "convenience" API to manage glyphs in "include/ftglyph.h". See the demo program "ftstring" for an example.. - the raster interface has been changed in order to allow direct composition through user-provided callbacks. This has been tested but isn't demonstrated for now in "demos" - the FT_LOAD_NO_RECURSE flag is supported, as this is required by some new code in the auto-hinting engine - some bug fixed in FT_MulFix which made FT_xxx_Transform return incorrect results..
